Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a chest strap device for correction in the monitoring of autonomous respiratory and circulatory technologies. Background Art

[0002] The corrective chest strap is a commonly used auxiliary device in the field of medical devices, mainly used for the thoracic fixation and support of patients after chest surgery. There are also plate-like objects provided in the chest strap for fixing or supporting body parts, which is highly applicable to patients with sternal or rib fractures. Traditional corrective chest straps are mostly made of elastic fabrics, which apply appropriate pressure by surrounding the chest cavity to help stabilize the surgical area, relieve pain, promote wound healing and prevent complications. Such chest straps play an important role in the postoperative rehabilitation of patients through functions such as chest cavity stabilization, wound protection, respiratory function assistance and posture correction. In recent years, with the development of medical technology, some improved chest straps with the function of monitoring autonomous respiratory and circulatory technologies have emerged on the market. Such chest straps can capture key physiological parameters such as the patient's respiratory rate, respiratory depth, heart rate changes, body temperature fluctuations and chest cavity movement conditions in real time through built-in sensors, enabling medical staff to timely understand the changes in the patient's physiological state and providing a scientific basis for clinical treatment decisions.

[0003] However, in clinical practice, some special patient groups (such as those caused by car accidents) who need to insert multiple drainage tubes after thoracic surgery and have sternal or rib fractures face severe challenges when using traditional corrective chest straps; such patients usually need to insert multiple drainage tubes simultaneously to drain gas, liquid or blood in the chest cavity. These drainage tubes are distributed at different positions in the chest cavity, and the distances between them are irregular and not fixed, but they must all remain unobstructed to ensure the drainage effect.

[0004] Chinese patent document (Publication No.: CN119454316A) discloses a structure of an intraoperative rib fracture reduction and fixation chest strap, including a wearable part, on which multiple fixing straps are sewn. One end of the fixing strap is hollow, and multiple protection plates are evenly distributed in a linear array inside one end of the fixing strap. Two connecting columns and two card slot grooves are symmetrically arranged at the opposite ends of the multiple protection plates respectively. Multiple triangular protrusions extend in a circular array on the outer surface of the connecting column, and the triangular protrusions are engaged inside the card slot grooves. Limiting ears are slidably sleeved on the outer sides of the two connecting columns near the triangular protrusions. The present invention can resist the external force of bumps to avoid secondary injury to the fractured ribs, which is beneficial to the patient's recovery. At the same time, it can also adapt to patients of different body types and effectively meet the wearing requirements.

[0005] For patients who have multiple drainage tubes inserted in the chest cavity and need to use a corrective chest belt to fix them, the spacing between the multiple drainage tubes is uncertain. It is difficult to avoid multiple drainage tubes at the same time when using a corrective chest belt, which will cause squeezing of the drainage tubes and affect the normal function of the drainage tubes. If the chest belt is adjusted to avoid the drainage tubes by winding and unwinding, the chest belt will be uneven when wound or unwound, and the edge will be permanently curled after multiple uneven tensions, resulting in idling or jamming when winding and unwinding, affecting the precise adjustment of the chest belt distance.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. For patients with multiple drainage tubes inserted into the chest cavity and in need of fixation using a corrective chest strap, the present invention realizes the avoidance between multiple drainage tubes at variable distances, avoids squeezing the drainage tubes, and ensures the normal function of the drainage tubes. Specifically, the device adopts a segmented chest strap structure design. The chest strap body is composed of multiple chest strap segments, and two adjacent chest strap segments are connected by an adjustment assembly. The adjustment assembly includes two winding and unwinding cavities arranged at intervals along the extension direction of the chest strap body. An accommodation groove is formed between the winding and unwinding cavities, and this accommodation groove is specifically used to avoid the chest cavity drainage tubes and prevent squeezing the drainage tubes; a rotating cylinder is rotatably arranged in each of the two winding and unwinding cavities, and the rotating cylinders are respectively fixedly connected to the ends of the adjacent chest strap segments; a power cavity is fixedly connected to the same side of the two winding and unwinding cavities, and a power assembly is arranged inside, and the power assembly is connected to a driving unit; when the motor of the driving unit is started, the two rotating cylinders rotate in opposite directions, and each of the two rotating cylinders winds and unwinds the chest strap segments, thereby changing the position of the accommodation groove on the chest strap body and realizing the avoidance of the drainage tubes at any position.

[0020] In the overall chest strap of the present invention, the width of the adjustment assembly in contact with the patient can be set according to the actual use situation; the number of adjustment assemblies can also be set. The plate-shaped adjustment assembly has a splint function and can further fix the body, especially for patients with sternal or rib fractures.

[0021] 2. When the adjustment assembly of the device of the present invention winds or unwinds the chest strap, it maintains the tension of the chest strap near the rotating cylinder, so that the chest strap always remains neat during the adjustment process, avoids idling or jamming of the rotating cylinder during winding and unwinding, and ensures the precise adjustment of the chest strap distance; specifically, the device adopts a pressure roller unit supported by a cross hinge rod structure and a tensioning unit adjusted by a spring to realize the balanced control of the tension of the chest strap during winding and unwinding, ensuring smooth and stable operation of the chest strap; the pressure roller unit includes two groups of cross hinge rods symmetrically arranged in the two winding and unwinding cavities. The second rotating shaft on the cross hinge rod is located at an eccentric position on the two hinge rods and is closer to the channel of the accommodation groove. During the process of the pressure roller clamping and tensioning and conveying the chest strap, a certain distance is maintained between the guiding rollers at the other end, which plays a transitional role, reduces the guiding angle of the chest strap, and ensures smooth winding of the chest strap.

[0022] The rotation of the rotating cylinder and the pressure roller is controlled by a motor to achieve smooth winding of the chest band. The structure is simple and easy to operate, effectively avoiding the permanent curling that easily occurs in traditional chest bands after multiple uneven tensions, and preventing idling or jamming during the winding process. It solves the problems of unevenness, idling or jamming that occur during the winding and unwinding of the chest band, ensures the accuracy and reliability of the adjustment of the position of the accommodation groove, provides a guarantee for the effective avoidance of the thoracic drainage tube, and at the same time ensures the normal functioning of the correction and monitoring functions of the chest band.

[0023] 3. In the present invention, a lifting rod with scale lines is screwed onto the rotating worm shaft, and the distance is displayed when the adjustment component moves, facilitating precise adjustment by medical staff. Specifically, the top end of the worm shaft extends towards the top of the power cavity and is provided with external threads. The top plate is provided with a limit sliding groove, and a lifting rod with an internal threaded opening matching the external threads is arranged. Scale lines are marked on the outer circumference. This design forms a precise screw lifting structure. The rotation of the worm shaft drives the vertical movement of the lifting rod, and the scale lines visually display the travel distance of the accommodation groove, facilitating precise adjustment by medical staff. Moreover, the self-locking characteristic of the worm and worm gear is utilized to ensure the stability of the adjusted position, and it will not shift even when the patient moves, solving the problem of precise positioning of traditional chest bands and providing a technical guarantee for the avoidance of the drainage tube.

In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0037] Figures 1 - 9As shown in the figure, a chest strap device for correction in the monitoring of autonomous breathing cycle technology includes a chest strap body. Separable connectors 13 are provided at both ends of the chest strap body. The chest strap body is composed of a plurality of chest strap segments 11. Two adjacent chest strap segments 11 are connected by an adjustment assembly 12. The adjustment assembly 12 includes two winding and unwinding cavities 19 arranged at intervals along the extension direction of the chest strap body. An accommodation groove 20 is formed between the winding and unwinding cavities; a drum 32 is rotatably arranged in each of the two winding and unwinding cavities 19. The drums 32 are respectively fixedly connected to the ends of the adjacent chest strap segments 11; a power cavity 16 is fixedly connected to the same side of the two winding and unwinding cavities 19. A power assembly is arranged in the power cavity 16. The power assembly is drivingly connected to the two drums 32 and makes the rotation directions of the two drums opposite; when the power assembly is started, the two drums 32 with opposite rotation directions respectively wind and unwind the chest strap segments 11 to change the position of the accommodation groove 20 on the chest strap body.

[0038] In the overall chest strap of the present invention, the width of the adjustment assembly in contact with the patient can be adjusted according to the actual use situation; the number of adjustment assemblies can also be set. The plate-shaped adjustment assembly has a splint function and can further fix the body, especially for patients with sternal or rib fractures.

[0039] In an embodiment of the present invention, the accommodation groove 20 is at the bottom of the adjustment assembly 12. A channel is provided on the side of the accommodation groove 20 away from the power cavity to facilitate the penetration of the drainage tube; the top plate 22 connects the two winding and unwinding cavities and the power cavity to form a stable structure. A control switch 14 is provided on the top plate 22 to control the start, forward and reverse rotation of the motor 21.

[0040] The correction chest strap device of the present invention includes a chest strap body and separable connectors 13 at both ends. The chest strap body is formed by connecting a plurality of chest strap segments 11 through an adjustment assembly 12. This design solves the problem in the prior art that there are multiple drainage tubes inserted in the chest cavity and a correction chest strap is needed for fixation. Among them, the adjustment assembly 12 can be set in multiple numbers according to the actual situation, not limited to Figure 1 the number in

[0041] The adjustment assembly 12 is the core of the device, including two winding and unwinding cavities 19 arranged at intervals along the extension direction of the chest strap body. An accommodation groove 20 is formed between the winding and unwinding cavities, which is used to avoid the chest cavity drainage tube and prevent extrusion of the drainage tube.

[0042] A drum 32 is rotatably arranged in each of the two winding and unwinding cavities 19. The drums are respectively fixedly connected to the ends of the adjacent chest strap segments 11. A power cavity 16 is fixedly connected to the same side of the two winding and unwinding cavities 19. A power assembly is arranged inside to make the rotation directions of the two drums 32 opposite. When the power assembly is started, the two drums 32 with opposite rotation directions respectively wind and unwind the chest strap segments 11, thereby changing the position of the accommodation groove 20 on the chest strap body.

[0043] The change in the position of the adjustment component of the present invention on the entire chest band structure facilitates placing the patient's drainage tube in the accommodation groove 20, avoiding squeezing the drainage tube, and ensuring the realization of the dual functions of guiding the patient's drainage tube and fixing the chest band. Importantly, by adjusting the position of the adjustment component 12 on the entire chest band, it can adapt to multiple drainage tubes with uncertain spacings, and the accommodation groove 20 forms an avoidance and protection.

[0044] Further, the power component includes a worm 24. A driving unit is arranged on the side wall of the power cavity 16, and the output end of the driving unit is connected to the worm 24. First rotating shafts 31 are respectively arranged in two winding and unwinding cavities 19, and a rotating cylinder 32 is fixedly installed on the first rotating shaft 31. The same ends of the two first rotating shafts 31 extend into the power cavity 16, and worm wheels 25 are respectively fixedly arranged at the ends. The two worm wheels 25 are located on both sides of the worm 24 and are both meshed with the worm 24. Channels are arranged at one ends of the two winding and unwinding cavities 19 away from the accommodation groove 20, and pressing roller units are arranged adjacent to the channels.

[0045] See Figure 4 and Figure 5 , the power component distributes the power of the driving unit to the two winding and unwinding cavities 19 through a worm and worm wheel structure, driving the two rotating cylinders 32 to rotate in opposite directions respectively. When the power component is started, the two rotating cylinders 32 with opposite rotations respectively wind and unwind the chest band segments 11, thereby changing the position of the accommodation groove 20 on the chest band body.

[0046] Among them, according to the chest band segments 11 already wound on the rotating cylinder 32, the rotation direction of the rotating cylinder 32 during unwinding or winding can be adjusted to ensure that the ultimate goal achieved by the two rotating cylinders 32 on both sides is that the two rotating cylinders on both sides respectively wind and unwind the chest band segments 11. It is not limited to the rotation directions in this embodiment, and the two can also rotate in the same direction.

[0047] Furthermore, the pressing roller unit includes a first pressing roller 18, a second pressing roller 17, and two groups of cross hinge rods symmetrically arranged in the winding and unwinding cavity 19. The cross hinge rod includes a first hinge rod 41 and a second hinge rod 42. The first hinge rod 41 and the second hinge rod 42 are rotatably installed on the second rotating shaft 37 in a cross shape. The second rotating shaft 37 is located at an eccentric position on the two hinge rods 42 and is closer to the channel of the accommodation groove 20. One end of the second rotating shaft 37 is rotatably installed on the side plate of the winding and unwinding cavity 19, and the other end is installed on the bottom of the winding and unwinding cavity 19 through a support seat. The first pressing roller 18 is installed on the two first hinge rods 41 close to the channel of the accommodation groove 20, and the second pressing roller 17 is installed on the two second hinge rods 42. Guide rollers 33 are arranged at the other ends of the first hinge rod 41 and the second hinge rod 42, and the two guide rollers 33 are both parallel to the pressing rollers.

[0048] See Figure 7, among the first pressure roller 18 and the second pressure roller 17 arranged on the same side, power is provided to one of the pressure rollers to rotate, which cooperates with the rotation of the rotating cylinder 32 on the same side to make the transmission speed of the transmitted chest strap segment 11 consistent with that of the rotating cylinder 32, avoiding the unevenness of the chest strap during winding or unwinding and maintaining the uniform tension of the edge part.

[0049] It should be noted that guide rollers 33 are arranged at the other ends of the first hinge rod 41 and the second hinge rod 42, and the two guide rollers 33 are arranged parallel to the pressure rollers. Due to the eccentric setting of the second rotating shaft 37 on the two hinge rods 42, when the first pressure roller 18 and the second pressure roller 17 approach and clamp the chest strap segment 11, there is a certain distance between the two guide rollers 33, which is beneficial for the smooth passage of the chest strap segment 11 while providing a guiding effect, playing a transitional role for the chest strap segment 11 between the rotating cylinder 33 and the pressure roller, and avoiding the influence of too large an angle on the tension.

[0050] Furthermore, tensioning units are arranged above the two groups of cross hinge rods. The tensioning unit includes a sliding sleeve 29 and a spring 38. The sliding sleeve 29 is fixedly arranged on the winding and unwinding cavity 19. A sliding rod 30 is inserted into the sliding sleeve 29. An articulated ear 39 is fixedly arranged at the end of the sliding rod 30 close to the cross hinge rod. Two connecting rods 43 are articulated to the articulated ear 39. The ends of the two connecting rods 43 far from the articulated ear 39 are respectively connected to the first hinge rod 41 and the second hinge rod 42 through articulated parts; a spring 38 is sleeved on the sliding rod 30 between the sliding sleeve 29 and the articulated ear 39.

[0051] See Figure 6 and Figure 7 , the tensioning unit mainly relies on the conversion of the elastic potential energy of the spring and mechanical connecting rod transmission to achieve. When the tension of the chest strap changes during winding and unwinding, through the cooperation of the sliding rod 30 and the spring 38, the sliding rod 30 can make an axial reciprocating motion in the sliding sleeve 29. The movement of the sliding rod 30 is transmitted to the first hinge rod 41 and the second hinge rod 42 through the articulated ear 39 and the connecting rod 43, thereby driving the first pressure roller 18 and the second pressure roller 17 to make corresponding position adjustments. Specifically, when the tension of the chest strap increases, the spring 38 is compressed, and the sliding rod 30 moves into the sliding sleeve 29, driving the hinge rod to adjust the position of the pressure roller through the connecting rod 43 to reduce the pressure on the chest strap; when the tension of the chest strap decreases, the spring 38 releases potential energy to push the sliding rod 30 to move outwards, driving the hinge rod to adjust the position of the pressure roller through the connecting rod 43 to increase the pressure on the chest strap, always keeping the chest strap in an appropriate tension state.

[0052] Tighten the transmitted chest strap segment 11, avoid the unevenness of the chest strap during winding or unwinding, maintain the uniform tension of the edge part, maintain the stable performance of the chest strap, further avoid idling or jamming during winding and unwinding, and ensure the precise adjustment of the chest strap distance.

[0053] It should be noted that the sliding rod 30 extends upward through the top plate 22, and an adjusting portion is provided at the end above the top plate 22 (see Figure 8 ). When the position of the chest strap segment 11 needs to be adjusted, by lifting the adjusting portion upward, the sliding rod 30, the hinge ear 39, and the connecting rod 43 are driven to rise, so that the cross hinge rod opens, increasing the distance between the first pressing roller 18 and the second pressing roller 17, and increasing the adjustment space of the chest strap segment 11.

[0054] Furthermore, the two second rotating shafts 37 close to the power cavity 16 respectively extend into the power cavity and are rotatably installed on the side plates. The two second rotating shafts 37 and the adjacent first rotating shafts 31 are respectively connected by a first pulley combination to form a transmission connection. Further, fourth pulleys 45 are provided on both sides of the accommodation groove 20. The two fourth pulleys 45 are arranged staggeredly on the rotating shafts of the side pressing rollers. One fourth pulley 45 is provided on the rotating shaft of the second pressing roller 17 on one side of the accommodation groove 20, and the other fourth pulley 45 is provided on the rotating shaft of the first pressing roller 18 on the other side of the accommodation groove 20; the two fourth pulleys 45 and the adjacent second rotating shafts 37 are respectively connected by a second pulley combination to form a transmission connection.

[0055] Refer to Figure 6 and Figure 7 , the first pulley combination includes a first pulley 34, a second pulley 35, and a first belt 36. The first pulley 34 is installed on the first rotating shaft 31, the second pulley 35 is installed on the second rotating shaft 37, and the first pulley 34 and the second pulley 35 are connected by the first belt 36 for transmission;

[0056] The first pulley combinations are symmetrically arranged on both sides of the accommodation groove 20 to transmit the driving force of the motor 21 to the second rotating shaft 37. Two third pulleys 44 are symmetrically arranged on both sides of the accommodation groove 20, and the third pulleys 44 transmit power to the next-level rotating shaft through belts and are not symmetrically arranged. One of the rotating shafts of the second pressing roller 17 and the first pressing roller 18 is selected staggeredly (see Figure 9 ), so that the chest strap segments 11 on both sides of the accommodation groove 20 are respectively formed with one side being wound and the other side being unwound, realizing the position change of the adjusting assembly of the present invention on the entire chest strap structure, which is beneficial to placing the patient's drainage tube in the accommodation groove 20, avoiding squeezing the drainage tube, and ensuring the realization of the dual functions of guiding the patient's drainage tube and fixing the chest strap. Importantly, by adjusting the position of the adjusting assembly 12 on the entire chest strap, it can adapt to multiple drainage tubes with uncertain distances, and the accommodation groove 20 is used to form an avoidance and protection.

[0057] Specifically, the second pulley assembly on one side includes a third pulley 44, a fourth pulley 45 and a second belt 46; the second pressure roller 17 is installed on the second hinge rod 42 through the third rotating shaft 40, the end of the third rotating shaft 40 extends outward and is fixed with the fourth pulley 45, the third pulley 44 is fixed on the second rotating shaft 37, and the third pulley 44 and the fourth pulley 45 are connected by the second belt 46;

[0058] It should be noted that when the first rotating shaft 31 rotates, the second rotating shaft 37 is driven by the first pulley combination, and the second rotating shaft 37 on one side drives the second pressure roller 17 on the same side to rotate, while the second rotating shaft 37 on the other side drives the first pressure roller 18 on the same side to rotate, so that the second pressure rollers 17 and the first pressure rollers 18 on both sides are transmitted alternately, so that the chest strap segments 11 on both sides of the accommodating groove 20 are respectively formed to be wound on one side and unwound on the other side, thereby realizing the position change of the adjustment component of the present invention on the entire chest strap structure.

[0059] By transmitting power to the pressure roller unit, the chest strap segments being reeled and unwound are always kept in a tensioned state, avoiding unevenness of the chest strap when reeling or unwinding, keeping the tension at the edge even, maintaining the stable performance of the chest strap, further avoiding idling or jamming when reeling or unwinding, and ensuring accurate adjustment of the chest strap distance.

[0060] Furthermore, the driving unit includes a motor 21, a worm 24 having a worm shaft 23, and a second bevel gear 27 is fixedly mounted on the end of the worm shaft 23; the motor 21 is fixedly mounted on the side wall of the power cavity 16, and a first bevel gear 26 is mounted on the output shaft of the motor 21, and the first bevel gear 26 meshes with the second bevel gear 27. Furthermore, the top end of the worm shaft 23 extends toward the top of the power cavity 16 and is provided with an external thread 28; a limiting slide groove 47 is provided on the top plate 22 of the power cavity 16, the limiting slide groove 47 is located above the worm shaft 23, a lifting rod 15 is provided in the limiting slide groove 47, a threaded opening is provided at the bottom of the lifting rod 15, the threaded opening is adapted to the external thread 28, and a scale line 48 is provided on the periphery of the lifting rod 15.

[0061] See also Figure 3 , Figure 4 , Figure 5 and Figure 8 The motor 21 is arranged outside the power cavity and located in the accommodating groove 20, which saves the installation space of the components and realizes the direction conversion through two bevel gears.

[0062] The top end of the worm shaft 23 extends towards the top of the power cavity 16, and an external thread 28 is provided at the extended end, which endows the device with the ability of precise positioning. A limit sliding groove 47 is formed on the top plate 22 of the power cavity 16, and the sliding groove is located directly above the worm shaft 23. A lifting rod 15 is arranged in the limit sliding groove 47, and a threaded port adapted to the external thread 28 at the top end of the worm shaft 23 is formed at the bottom of the lifting rod 15. When the worm shaft 23 rotates, due to the characteristics of threaded connection, the lifting rod 15 will move up and down in the limit sliding groove 47. For the convenience of precise positioning and recording, scale lines 48 are arranged on the outer periphery of the lifting rod 15. By observing the position of the scale lines, medical staff can accurately understand and control the position of the accommodating groove 20 on the chest strap body.

[0063] The design of the drive unit and the lifting rod has the following advantages: First, the bevel gear transmission structure is compact. Using a 90-degree power transmission method, it realizes the efficient transmission of the motor power to the worm shaft within a limited space, improving the overall transmission efficiency. Second, the meshing of the worm and the worm gear belongs to self-locking transmission. When the motor stops, the worm and the worm gear remain meshed, preventing reverse transmission and ensuring the stable position of the accommodating groove 20 without accidental displacement even under the movement of the patient or external force. Third, the cooperation between the external thread at the top end of the worm shaft and the threaded port at the bottom of the lifting rod forms an accurate screw lifting mechanism. By rotating the worm, the lifting rod makes a vertical movement in the limit sliding groove. The design of the scale lines on the outer periphery of the lifting rod facilitates precise adjustment according to the specific position of the patient's drainage tube, ensuring that the drainage tube is not squeezed. Finally, the coordinated work of the entire drive and positioning system solves the problems such as unevenness, idling or jamming that occur during the winding and unwinding of the traditional chest strap, ensuring the accuracy and reliability of the position adjustment of the accommodating groove, providing technical support for the effective avoidance of the thoracic drainage tube, and at the same time ensuring the normal function of the chest strap correction and monitoring, greatly improving the clinical practical value of the device.

[0064] It should be noted that the scale 48 markings are determined through the conversion relationship between the vertical displacement of the lifting rod 15 and the rotating cylinder 32; Rotating bearings are arranged between the worm shaft 23 and the top plate 22 and the bottom plate, which is beneficial to the stability of the transmission structure.

[0065] Furthermore, the connecting member 13 is a sticky fastener, and the sticky fastener includes a hook surface part and a plush surface part that cooperate with each other. The chest strap is fixed and adjusted through the detachable connection between the hook surface and the plush surface.

[0066] The hook-and-loop connection provides the ability of stepless adjustment. Compared with the traditional buckle or snap connection methods, the hook-and-loop can achieve connections at any position within the entire overlapping area, which enables the tightness of the chest strap to be precisely adjusted. The hook-and-loop connection maintains a certain elasticity while fixing, which can appropriately buffer the expansion and contraction of the chest caused by the patient's breathing, avoiding excessive restriction of the breathing movement and being more in line with the ergonomic principle.

[0067] Further, a sensor (not shown in the figure) is provided at the bottom of the adjustment assembly 12, and an external interface is provided on the side wall of the adjustment assembly 12. The external interface is electrically connected to the sensor.

[0068] The sensor is installed at the bottom of the adjustment assembly 12, close to the patient's chest, and can directly collect the patient's physiological signal data. According to the functional positioning of the device, these sensors may include a respiration monitoring sensor, a heart rate monitoring sensor, a body temperature sensor, and a thoracic activity monitoring sensor, etc. Through these sensors, the device can real-time capture key physiological parameters such as the patient's respiration rate, respiration depth, heart rate changes, body temperature fluctuations, and thoracic movement conditions. These data are transmitted to the external interface on the side wall of the adjustment assembly 12 through internal circuit connections. The external interface serves as a data output port and can be connected to an external monitoring device or a data processing system.

[0069] By real-time monitoring of the patient's respiratory and circulatory parameters, medical staff can timely understand the changes in the patient's physiological state. Especially for patients after chest surgery or thoracic drainage, the monitoring of respiratory function is particularly important, which helps to detect potential complications at an early stage, such as respiratory depression, increased pleural effusion, or unsmooth drainage, etc. The design of the external interface enables continuous data output to a bedside monitoring system or a telemedicine platform, realizing continuous monitoring of the patient, reducing the workload of medical staff, and improving the monitoring efficiency. The integrated design of the sensor and the chest strap adjustment assembly ensures that while adjusting the position of the accommodation groove to avoid the drainage tube, the monitoring function is not affected, guaranteeing the continuity and accuracy of data collection.
